One remark
In most cases these will be used in a classroom, where in most cases there won't be wireless network or internet available. It enables the pupils to exchange files etc. etc.

AFAIK these where never meant to bring internet to these rural areas. (just share it where it could be available).

You're solution would work in a dense environment where lots of people would be living in a confined area. Unfortunately most of these kids live in rural area's and sometimes have to walk several miles before they get to school.

So in theory, you're solution would work (if enough money available). But in practice it would only make the solution more expensive and depending on the availability of electricity (which might be more easily available in the future, but currently solar panels are still expensive).

Your example cited is not client-side peer-to-peer mesh  georgeou | 09/27/07
Re,  tombalablomba | 09/25/07
